Graphene: Will Nokia Be First To Market?

Graphite-Graphene-News-208BSo where is Nokia in solving practical graphene sensor development problems. Who knows? Probably only their R&D guys and partner companies.

But let’s hope they are pretty close, because thinner sensors with bigger megapixel count could really help all those coming PureView devices.

Just about every week we get a  major news release from a lab somewhere in the world, announcing a new properties or handling breakthrough regarding 21st century super-material graphene, or its cousin nano-carbon. Graphene in its present form was first discovered back in 2004, and eight years on, the first early usage, “simpler” commercial uses should soon begin coming to market. Of course it takes time and money to gear up for industrialisation, and we’ve only recently come up with new, cheaper, scalable ways of producing the right sort of graphene, but I suspect that from next year we are going to increasingly see some commercial announcements covering graphene.

Will Nokia be first, or at least among the first with its patent applied for graphene based photos sensors?  This knowledgeable writer at thinks that Nokia might be close. At almost 63, I’m a little too old for the geek scene, remaining “the bigger picture” dinosaur, but if anyone’s tracking the gadget sector, feel free to chip in with other candidates.  Perhaps RIM has something graphene up its sleeve?

After PureView, what’s next frontier for Nokia imaging? How about graphene based photo-sensors
By Staska on 16 Aug 12

Nokia’s PureView technology is already at the forefront of smartphone imaging. What may come next to make it even better?

How about graphene based photo sensors?

I am not sure how far along on the way to commercialization this technology is, but Nokia R&D is busy developing a graphene photo-detector, and already filed a patent for it.

The patent describes photo-detector/pixel with graphene photon collecting layer, a number of finger shaped electrodes placed above it to collect electrons-holes generated by passing light photons, a graphene nano-ribbon acting as field effect transistor to amplify the resulting current and transfer it to the connected control electronics. Several light detecting and amplifier layers can be stacked on top of  each other, with color filters in between, so different colors can easily be detected by each pixel in the sensor.
